Welcome to the email version of magicGNSS/PPP (Precise Point Positioning),
now processing static and kinematic GPS and GLONASS real-time data in RINEX format.
Only dual-frequency PPP is supported at the moment.
Real-time GPS and GLONASS orbits and clocks needed by PPP are generated internally. Satellite clock rate is 5 min. Rapid and final GPS orbits and clocks from IGS are also used, if available. Final IGS clock rate is 30 sec.
Please follow these instructions:
Send an email to email@example.com with the Subject Static or Kinematic and one RINEX observation file attached (or a maximum of two files for static PPP).
The attached files must be in standard or Hatanaka RINEX 2.10 or 2.11 format, compressed or not.
The files can be compressed in the following formats: .Z, .gz, .zip.
The filenames must follow the RINEX filename convention: daily, hourly, 15-min; if your file is compressed, you must keep the RINEX filename extension and the compression extension (for example vill3120.09o.gz is a valid name, but vill3120.zip is an invalid name; beware of Windows compression!)
The RINEX data rate must be one of the following, in seconds: 30, 15, 10, 5, 1.
The RINEX file must contain all of the following observables: P1 (or C1), P2, L1, L2.
The “APPROX POSITION XYZ” record on the RINEX file header is mandatory, but the values can be zero (if in doubt, set all values to zero).
GPS data earlier than 2000/05/03 cannot be processed, and GLONASS data earlier than 2010/01/01 cannot be processed.
In static PPP, if you attach two RINEX files and they belong to the same station, you will also get the comparison of the two PPP results (difference of coordinates).
Kinematic PPP can be used in two modes: Terrestrial and Aeronautical (default). This is configured within the email body, for example:
Virtual PPP (static) is also supported for IGS stations (no need to attach RINEX files!), just send an email to firstname.lastname@example.org with the Subject Virtual and a maximum of two virtual RINEX files in the body of the message, with the following syntax:
where ssss is the station name, yy is the two-digit year, and ddd the day of year. For example:
For mixed RINEX files (type "M") containing GPS+GLONASS observations, it is possible to process GPS-only, GLONASS-only, and GPS+GLONASS in PPP. This is configured according to the email Subject:
Static/Kinematic/Virtual = GPS+GLONASS
Static/Kinematic/Virtual M = GPS+GLONASS
Static/Kinematic/Virtual G = GPS-only
Static/Kinematic/Virtual R = GLONASS-only
